Unable to start my Lenovo laptop

Angie,
We appreciate your efforts but we apologize for the difficulties. To fix this issue, we request you to restart the computer in safe mode with networking. Before restarting the computer, make sure to unplug all the USB cables (eg: Printer, Scanner, HDD) then try to reboot the computer and try pressing “Esc” or “F8” key to check whether it skips to boot screen. If you face any difficulties in rebooting your device, we recommend you to contact the local technician or system manufacturer and get help to boot your device in safe mode. Thank you for your better understanding!

Angie I had the same problem as you, and tried everything. I was about to give up when I found the solution. 
When my computer starts up for 2 or 3 secs the manufacturer's name comes on with the possibility of Tab or Del. I pressed Del and amazingly my welcome screen came up. I logged in and immediately deleted the  AVG program causing the problem. My computer is now OK. I hope your computer gives you this Del option.

I am unable to start up my Lenovo laptop. When I power on, AVG starts to scan but gets stuck and leaves me on a page saying 'repairing disk errors. This might take over an hour to complete'. It never moves on from this page. I am on WIndows 10 and have tried to enter safe mode with F8 or escape or F2 button after starting laptop but nothing works. I do not have a recovery disk. Any ideas please?
